[Freeswitch-users] how to extract messages(SIP) from large pcap file.

[ik]

In wireshark, you can choose to follow UDP (or TCP) stream, and then you
can export that UDP stream to a new pcap file.

BTW, when capturing stuff on pcap related tool, you can create multiple
files based on some rules, such as size of file, or even timestamp like so:
tcpdump -nq -s 0 -A -vvv -i eth0 -G3600 -w /tmp/trace/sip-%F--%H-%M-%S.pcap

The -G is the number of seconds that the file will be rotated.
